(4-Arylsulfamoyl)phenylcarbamic acid esters: I. Synthesis and activity against herpes viruses

Aiming to modify the biological activity of sulfonamides, a number of alkyl (4-arylsulfamoyl)- phenylcarbamates were prepared in 50–70% yield. Biological screening showed that the target compounds possessed a high activity against herpes viruses as well as a traditional antibiotic one.

The Preparation of Sodium 4-Amino-3-nitrobenzenesulfonate and Some Related Compounds

The sodium salt of 4-amino-3-nitrobenzenesulfonic acid (o-nitroaniline-p-sulfonic acid) has been prepared by the action of dilute sodium hydroxide solution on ethyl carbamate.Central to this synthesis is the finding that the N-ethoxycarbonyl group, when located ortho to a nitro group (but not to a bromo group), is readily removed by dilute sodium hydroxide solution.
